CARBURETING DEVICE FOR EXPLOSlVE-ENGINES.

SPECIFICATION forming part of Letters Patent N0. 749,315, dated January 12, I904.

App1ication filed February 20,1902. Serial No. 94,881. (No model.)

A represents the carbureter-casing, and 31 a reservoir or supply-tank, which must be gastight. This characteristicin the construction shown grows out of the fact that the single inletto this tank may be hermetically sealed by a suitable cover or cap, 31. This reservoir must be elevated with reference to the vaporizing-chamber, to which the liquid hydrocarbon flows by gravity from the reservoir 31 through a feed-pipe 29 when the cock 29 therein is opened.

The carbureter casing consists of three parts-namely, the bottom member 1, the mid-L dle member 5, and the top member 6. There are rabbets 3 and 8 formed, respectively, in

the edges of the vertical portions 2 and -7 of the bottom and top members of this casing, which rabbets respectively receive the lower and upper edges of the outer shell of the middle member 5, and these three parts are connected together by means of bolts 11, which engage with laterally-projecting external ears 9 and 10 on the lower and upper members of the casing. 1

i In the middle member 5 is a centrally-placed vaporizing-chamber 12, whose walls 14 incline outward and upward and at their upper ends are curved inward and downward, as at 15 and 16. The bottom of this vaporizing-chamber extends below the inclined wall 1 forming what may be called a sediment-chamber 13, into which the impurities in the gasolene settle and from which they may be withdrawn from time to time through a drain-pipe 37 having a cook 38. In this middle section 5,

1 extending around and under the vaporizingchamber, is a cored-out annular recess 5. The

exhausted or exploded gases discharged from the engine enter this annular chamber through the opening 40 and pass out through the outlet 41, having in the meantime heated the hydrocarbon liquid in the vaporizing-chamber and brought it more nearly to the vaporizing temperature.

An air-tube 22 passes down centrally through the top of the casing, its lower end being extended a short distance down into the vaporizing-chamber, said lower end being in a plane der the lower edge of said tube.

only a little above the plane in which the top surface of 'the liquid hydrocarbon will lie. Through this tube 22, near the upper end thereof, are a plurality of holes 24, said holes being of such size and number that approximately the desired volume of air for mixing with the hydrocarbon gas may pass through them. In the lower end of this tube there may be other holes 23, through which some of the air may pass into the vaporizing-chamber, such air being additional to that which passes unrepresents a pipe which, together with the feedpipe 29, passes through a hole in a plug 25, which closes the upper end of the tube 22. The lower end of this pipe extends into the vaporizing-chamber and lies in the plane substantially in which it is desired to maintain the surface-level of the hydrocarbon. This pipe 30 extends up to the reservoir, with which it is connected in such wise that its open upper end is in the tank above the liquid therein.

The casing A has a lateral discharge-neck 42, with which a pipe may be connected, which leads to the explosion-chamber or delivery,-

- point of the explosive mixture. In the operation of this device when properly connected with an explosion-engine the operation of the piston sucks the explosive mixture through this neck 42 out of the casing. This of course causes air to be drawn into the casing through the holes 24 and down through the tube 22, which air as it emerges from the lower end of this tube strikes directly upon the surface of the hydrocarbon liquid, in the vaporizingchamber, thereby agitating it to some degree and accelerating its vaporization. The air and the gas thus generated will be forced laterally and will follow the inclined sides 14 and will be turned back upon itself by the overhanging wall 15, and thereby will become pretty thoroughly mixed, and this mixed gas will flow out of the vaporizing-chamber around the tube 22. One or more wire screens 36 are stretched across the top of the vaporizing-chamber and around the tube 22. It is therefore necessary that this air and gas shall pass through said screen or screens, wherefore the mixing of the air and gas will be more completely effected. Through the top of the casing are a pluralityof holes 32, and surrounding the tube resting upon the casing is a movable plate 33, having a plurality of holes 34, which may register with the hole 32, thus admitting to the casing more or less air, depending'upon the position of said plate. This air will be more or less completely commingled with the explosive mixture produced in the vaporizing-chamber, before explained, and is admitted in the necessary quantity to supply any deficiency-of air admitted from tube 22. The space'in the upper part of the casing communicates with the space in the lower part thereof through a plurality of passages 18". A drain-pipe 43 is connected with the lower part of the casing, wherefore if the casing is flooded with the gasolene through the improper operation of any of the described mechanism all of the gasolene outside of the vaporizing-chamber may be drawn off.

As the gasolene in the vaporizing-chamber is vaporized and the surface-level thereof falls as a result the lower end of the tube 30 will become uncovered. This will permit air to flow through it into the reservoir 31, and this permits a corresponding flow of the gasolene from the reservoir through the feed-pipe 29 to the vaporizing-chamber, which flow is not possible normally, because the lower end of the pipe 30 is sealed by immersion in the gasolene and there is no other channel through which air may be admitted to the reservoir 31.

In the modified form of the carbureter shown in Fig. 7 the lower member of the carburetercasing contains the vaporizing-chamber 12. The middle member 5 is a simple cylinder, of glass, whose ends fit in rabbets 3 and 8 in the ends of the lower and upper members of the casing, and the three members are connected by bolts 11, engaging in ears 9 and 10. An air-tube 22 extends through the top of the upper member and down into the vaporizing-chamber and has the air-inlet holes 24 near its upper end. The gasolene-feed pipe 29* and the air-pipe 30 extend down through the plugged upper end of t be22 into the vaporizing-chamber, as do the ocrresponding pipes 29 and 30 of the other construction, it being the intention to connect the upper end of said pipes with a gas-tight gasolene-reservoir, as before explained. In the side of the upper member 6 are the perforations 32, and around the said perforated member is aperforated sleeve 33 whose perforations 34 may register with the perforations 32, or said sleeve may be turned to more or less completely close said perforations. The outlet for the explosive mixture is through the neck 42.
